Robyn Denholm was named as chairwoman of Tesla, as part of a deal with regulators under which Elon Musk is relinquishing the role at the electric-car manufacturer. Denholm is the chief financial officer at Telstra, an Australian telecoms firm. She will be the first person at Tesla other than Musk, who remains chief executive, to sit at the apex of the company since its very earliest days.

SoftBank reported a big jump in quarterly net profit, to ¥526.4 billion ($4.6 billion). That was mostly because of returns from technology investments in its Vision Fund.

Its share price has fallen by a fifth following the killing of the Saudi journalist, allegedly by Saudi government operatives.

The political maneuvering continued in the trade war between the U.S. and China. Wang Qishan, a senior Chinese official, indicated that Beijing was ready for a discussion about "mutual concerns" with Washington.

Xi and President Donald Trump are expected to discuss how they might end their standoff when they meet at the G-20 summit this month.

U.S. prosecutors brought criminal charges against two former bankers at Goldman Sachs and a Malaysian financier in connection with the alleged misappropriation of funds from Malaysia's 1MDB development fund (one of the bankers has pleaded guilty).

The share prices of Italian banks came under renewed pressure, ahead of a deadline for the Italian government to submit a revised budget that meets E.U. rules.

After pulling out of a nuclear deal with Iran earlier in the year, the United States' most punishing sanctions on the country came into effect, aiming to cripple its already struggling economy.

Despite a U.S. call for peace talks, the war in Yemen escalated, as forces backed by a Saudi-led coalition advanced on rebel positions in the port city of Hodeida.
